0f the plate taken along the l nes 65 of Fig. and 6, the recess orgroove 23 is positioned cen- 55 trally of the length of the bed plate l6by means of an aperture 24 through the size plate 20 which fits over apin 25 projecting from'said bed plate. A screw threaded hole 26 isdrilled through the size plate 20 for the connection of a tool tofacilitate removal of said plate from the channel I1.

Plates 1 9 and 2|, which I term end plates, are retained exteriorly ofthe ends of the size plate 20, and each plate has on its surface aprojeca tion 28 which constitutes one element of a cooperating embossingdie and provides for cooperation with recesses in the forming die aswill be later described.

Referring to Fig. 6, the outer ends of the size plate 20 and the innerends of the end plates l9 and 2| are rabbeted as shown at 29, and pins30 carried by the end plates project through apertures 3| in the plate20 to secure the respective plates together. By reason of suchconnection, the end plates may easily be removed in order that sizeplates of various lengths according to the size of collar being foldedand marked may be inserted. It will be apparent that the length of thesize plate 20 will determine the position of the end plate projections28.

In Figs. 1 and 4 the forming die I is shown as comprising end sections32 and 34 and central section 33, rigidly carried respectively byforming die section carriers 35, 3'! and 36. Sections 32 and 34 have atone end on their under surface projections 38 and 38, respectively, eachprojection being adapted to cooperate with one of the recesses orgrooves 22 in plate 18 when the die is lowered and the bed plateelevated to form indicating marks or impressions on the folded edge ofthe blank, said marks or impressions denoting points on the blank wherethe ends of the collar top are to be attached.

The opposite edge of sections 32 and 34 are provided with recesses orslots 39 and 40, respectively, which are adapted to cooperate withprojections 28 on the plates 19 and 2!, respectively, to form indicatingmarks or impressions on the folded edge of the collar blank, said marksor impressions designating the points of attachment of the blank to theshirt collar band at the shoulder seams.

Section 33 has in one edge on its under surface a projection 4|, whichwith recess or groove 23 in the size plate 29, constitutes an embossingdie to make an indicating mark or impression on the folded edge of theblank to designate the center thereof.

The central section carrier 36 is fixedly mounted to an angle bar 42 bya bolt 43, as shown in Fig. 8. As indicated in Figs. 1 and '7, sectioncarrier 31 is adjustably mounted on angle bar 42, the latter beingrigidly secured to a top plate 44 by means of bolts 45. Carrier 31 maybe adjusted longitudinally along angle bar 42 and secured thereto bymeans of bolts 46 passing through slots 41 in the angle bar, andscrewing into spaced threaded apertures 48 in carrier 31. Thisadjustment serves to place projection 38 with reference to a selectedrecess or groove 22 for the proper collar size, and to likewise placerecess 40 with respect to projection 28.

Carrier 35 is adjustably mounted to an angle bar 49 in the same manneras is carrier 31 to angle bar 42, but angle bar 49 is movably attachedto top plate 44, this movement being longitudinal of top plate 44, andbeing controlled by the pressure of a spring 59 which is fastened at itsends to angle bars 49 and 42.

As shown in Fig. 1, a portion of the inner end surface of angle bar 49constitutes a cam surface while a portion 52 of one end surface of anglebar 42 also functions as a cam surface. This arrangement of cam surfacesis clearly shown in my prior Patent No. 972,320, granted October 11,1910.

Referring to Fig. 2, a link 53 has a pivot 54 adjacent pivot 12 andcarries at its opposite end a cam 55, said cam cooperating with camsurfaces 5| and 52 to move angle bar 49 carrying forming die section 32outwardly with respect to angle bar 42 and forming die section 33 whenthe die I head is lowered, spring 50 serving to return angle bar 49 andforming die section 32 to their inner position when the die head israised and cam 55 is retracted. This contraction of the forming dieafter the infolding operation serves to facilitate the stripping-of theinfolded blank from the forming die.

In preparing the machine for operation on the desired size of collarblank, the proper size plate 20 is secured in the bed plate, and the endplates l9 and 2| are secured thereto. The die head is then lowered as inFig. 2, angle bar 49 being moved to its outer position by cam 55, afterwhich projections 38' and 38 are lined up above the selected recesses orgrooves 22, (as shown in Fig. 5), by adjusting carriers 35 and 3! alongangle bars 49 and 42, respectively, and securing the carriers by bolts46. Obviously, recesses 39 and 40 will be likewise aligned by thisadjustment above projections 28, as shown in Fig. 6.

In operation, the die hard is raised, a blank of material is centered onthe bed plate, and the die head is lowered, placing the forming diecentrally of the blank. By suitable mechanism well known in the art, theinfolding plates are moved into fold the edges of the material over theedges of the forming die, and while the infolding plates are in theirinward position, heated bed B carrying bed plate 16 is elevated by afoot treadle to press or crease the infolded edges of the blank betweenthe bed plate and the infolding plates, and over the edges of theforming die, the complementary projections and recesses on the formingdie and bed plate serving to emboss the folded edge of the material withproperly spaced indicating impressions.

Obviously, the details of the preferred embodiment described may bemodified materially without departing from the spirit of the invention,

more, a reversal of the arrangement of the projections on and therecesses in the forming die and bed plate is contemplated, or, theprojections might all be on the forming die and the recesses all in thebed plate, or vice versa.

I claim:

1. In a machine of the class described, a material supporting bedprovided with a channel, plates having recesses and projections in saidchannel, forming dies provided with projections and recesses, andinfolders adapted to infold a blank of material, said recesses andprojecjections, respectively, being complementary and adapted to producea plurality of indicating marks on the infol-ded blank of material.

' 2.
